Forward VNC service port 5900 to host by

docker run -p 6080:80 -p 5900:5900 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
Now, open the vnc viewer and connect to port 5900. If you would like to protect vnc service by password, set environment variable VNC_PASSWORD, for example

docker run -p 6080:80 -p 5900:5900 -e VNC_PASSWORD=mypassword -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
A prompt will ask password either in the browser or vnc viewer.

HTTP Base Authentication
This image provides base access authentication of HTTP via HTTP_PASSWORD

docker run -p 6080:80 -e HTTP_PASSWORD=mypassword -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
SSL
To connect with SSL, generate self signed SSL certificate first if you don't have it

mkdir -p ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ssl/nginx.key -out ssl/nginx.crt
Specify SSL port by SSL_PORT, certificate path to /etc/nginx/ssl, and forward it to 6081

docker run -p 6081:443 -e SSL_PORT=443 -v ${PWD}/ssl:/etc/nginx/ssl -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
Screen Resolution
The Resolution of virtual desktop adapts browser window size when first connecting the server. You may choose a fixed resolution by passing RESOLUTION environment variable, for example

docker run -p 6080:80 -e RESOLUTION=1920x1080 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
Default Desktop User
The default user is root. You may change the user and password respectively by USER and PASSWORD environment variable, for example,

docker run -p 6080:80 -e USER=doro -e PASSWORD=password -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
Deploy to a subdirectory (relative url root)
You may deploy this application to a subdirectory, for example /some-prefix/. You then can access application by http://127.0.0.1:6080/some-prefix/. This can be specified using the RELATIVE_URL_ROOT configuration option like this

docker run -p 6080:80 -e RELATIVE_URL_ROOT=some-prefix dorowu/ubuntu-desktop-lxde-vnc
NOTE: this variable should not have any leading and trailing splash (/)

Sound (Preview version and Linux only)
It only works in Linux.

First of all, insert kernel module snd-aloop and specify 2 as the index of sound loop device

sudo modprobe snd-aloop index=2
Start the container

docker run -it --rm -p 6080:80 --device /dev/snd -e ALSADEV=hw:2,0 dorowu/ubuntu-desktop-lxde-vnc
where --device /dev/snd -e ALSADEV=hw:2,0 means to grant sound device to container and set basic ASLA config to use card 2.
